If it high school physics, I am sure you can site some sources of all this information, since you got an A and all. You could be right and everyone else could be completely off base. Most of this stuff is above my pay grade, but I do know credible sources (Hint, wickepedia is not a credible source). Other than that, what your saying is just blah blah blah. Your example of Sagan was ridiculous, since whenever he goes head to head with the big time sprinters, he usually doesn't win. I don't think he won a single stage last year in The Tour. Slow circles doesn't prove that will be the same outcome at speed. When riding slow, a rider turns the handle bars in the direction they want the bike to go. Do that on a 60 mph descent and you will crash. You need to counter steer. Keith Code talks about this in both his books. That is an example, by the way of citing one's source.
